General Description

The MAX1329/MAX1330 are smart data acquisition sys-

tems (DASs) based on a successive approximation

devices are highly integrated, offering an ADC, digital-

to-analog converters (DACs), operational amplifiers (op

amps), voltage reference, temperature sensors, and

analog switches in the same device.

The MAX1329/MAX1330 offer a single ADC with a refer-

ence buffer. The ADC is capable of operating in one of

two user-programmable modes. In normal mode, the

ADC provides up to 12 bits of resolution at 312ksps. In

DSP mode, the ADC provides up to 16 bits of resolution

at 1000sps. The ADC accepts one external differential

input or two external single-ended inputs as well as

inputs from other circuitry on-board. An on-chip pro-

grammable gain amplifier (PGA) follows the analog

inputs, reducing external circuitry requirements. The

PGA gain is adjustable from 1V/V to 8V/V.

The MAX1329/MAX1330 operate from a 1.8V to 3.6V dig-

ital power supply. Shutdown and sleep modes are avail-

able for power-saving applications. Under normal

operation, an internal charge pump boosts the supply

voltage for the analog circuitry when the supply is < 2.7V.

The MAX1329/MAX1330 offer four analog programmable

I/Os (APIOs) and four digital programmable I/Os

(DPIOs). The APIOs can be configured as general-pur-

pose logic inputs and outputs, as a wake-up function, or

as a buffer and level shifter for the serial interface to

communicate with slave devices powered by the analog

supply, AV

. The DPIOs can be configured as general-

purpose logic inputs and outputs as well as inputs to

directly control the ADC conversion rate, the analog

switches, the loading of the DACs, wake-up, sleep, and

shutdown modes, and as an interrupt for when the ana-

log-to-digital conversion is complete.

The MAX1329 includes dual 12-bit force-sense DACs

with a programmable reference buffer and one op amp.

The MAX1330 provides one 12-bit force-sense DAC with

a programmable reference buffer and two op amps. For

the MAX1329/MAX1330, a 16-word DAC FIFO can be

used with the DACA for direct digital synthesis (DDS)

of waveforms.

The 4-wire serial interface is compatible with SPI™,

QSPI™, and MICROWIRE™.
